Capture Audio via Digital in Port?

This seems like a basic issue, but I can't find the answer - Is there a way to set my audio capture / input to come in via the Digital in port (TOSLINK, S/PDIF)? I'd like to do this separately from the video capture input. I've found connection information in the FCP documentation, but haven't been able to figure out the settings in the software.
Thanks!

Thanks for the info. So, just to be clear I'll have to run the source twice, once to capture using one of the audio apps and once in FCP to capture the video? I won't be able to capture audio / video at the same time using FCP (audio from the Digital in port and Video from my BlackMagic card)?

You could connect a FireWire Blu-Ray drive and use non-Apple player software.

Cannot Capture Audio via AJA IoHD

I suddenly cannot capture audio via my AJA IoHD. I am using a JVC ProHD deck which connects through SDI to the IoHD and then into the Mac via FW800.
The system audio is routed to the IoHD. FCP AJA IoHD 720p 59.94 Apple ProRes 422 (HQ) easy setup is selected. Capture Clip Settings are set to capture 8 channels of audio, 48Khz 24 Bit.
I've got to be missing something. Previously captured clips have audio and playback no problem. I can see it in the meters.
Now when capturing I can hear the audio but nothing registers on the meters and once captured there is no audio on the clip.
I cannot think of what I am missing. I've been racking my brain and pounding my fists for hours. (That hasn't worked either)
Any ideas?

Yes... forgot to mention that the audio box is checked in the log clip settings pane. It behaves as if it isn't though.
I just called Apple support and they were decidedly unhelpful.

Mac Mini (Intel) - No audio via digital optical

My audio was working fine previously with a standard stereo cable, but today I've tried switching to an optical cable and the sound no longer works. If I watch the Sound preference pane as I connect and disconnect the optical cable, I can see it switching between Headphones (old/stereo cable) and Digital output. Based on some other threads I've found on this subject I've also tried launching Audio MIDI Setup, and in the output section it just has the message "Output is not supported".
Has anyone come across this issue?
For reference it's a 1.83ghz Intel Mac Mini running Leopard 10.5.2.
Thanks,
Tom

I'm reasonably certain it's not the Pioneer as I have other digital components (1 optical, 2 coaxial) connected to it and working perfectly. I'm also fairly comfortable that the plug is activating digital as I can see it change in the preference pane when I insert the plug (removing it goes back to internal, and inserting the stereo cable switches to Headphones).
I'm concerned by the fact that no light is visible from the port, even when the optical mini adapter is inserted by itself (without the toslink plugged into it). On the Macbook Pro red light was always visible when the port was active, as it is on other components I have. Can anyone confirm if you can see the light emitting from yours?

Unable to capture audio from BlackMagic HD Extreme via Voice Over tool

Hi !
I'm trying to capture audio via my BlackMagic HD Extrem card using the Voice Over tool in FCP6, but I can't, no audio is incoming.
I can ingest audio with video using log and capture, then I know my card and my cables are working.
I tried to set the BM card as audio input in my Audio's System Prefereces Pane, but it isn't working either.
I've been looking on the BM website, but I found nothing.
Can you help me ?
Thx

Thanks for the reply.
Looking at system preferences I found that audio input was set microphone. Don't know how it happened. I switched it to DeckLink and now FCP displays 16 input channels in Log and Capture dialog. I didn't try to capture yet but I think it solved the problem, because before I had only two channels displyed.

No audio via Mini-DisplayPort. MBP 5,5

Hello,
I have the MBP 5,5 and I am trying to connect it to my TV via the Mini-DisplayPort HDMI adpater.
I am getting video but not audio any idea?
Any help is appreciated.
Thanks,

A 2009 MBP does not support audio via the minidisplay port. For audio you will have to tap the audio output port and use RCA connectors to the audio inputs on the TV.
Ciao.

How do I select ports for capturing audio?

Summary:
I am working on a project that needs to programmatically query the sound system and present the user with a list of choices of input lines (Port) to be captured (just one input at any time), with the ability for the user to control the volume of the selected input line (Port).
It seems that either:
a) I'm not querying the sound system correctly to get the information needed to do what I want
b) I don't understand the way the system is intended to present a logical description of the sound system
c) My system is bizarre
d) The (only) way I can think of to make this work is actually the correct way - and will be subject to failure on different machines.
I hope it's either option a) or b) - I can fix that; c) is a nuisance, but d) is a worry.
Discussion:
What I've found is that all 3 source Ports reported by AudioSystem queries are associated with Mixers that do not support TargetDataLines (each such Mixer presents a description of "Port Mixer"). It appears for each of the three (source) Port Mixers on my system, there is another logically distinct Mixer (each such Mixer presents a description of "Direct Audio Device: DirectSound Capture") that is somehow connected to the source Port Mixer. The only thing that I can find that indicates any connection between the two Mixers is the naming of the two Mixers: the Port Mixer is named "Port <someName>" and the Direct Audio Mixer is named "<someName>" (without the "Port" prefix). I confirm this logical connection between the two mixers by noting that when I read from a TargetDataLine on the Direct Audio Mixer I am capturing the audio present on the source Port of the similarly-named Port Mixer.
I'd be happy to just use the TargetDataLine from the Direct Audio Mixer and ignore the Port Mixer, but there are no controls on the former and I need to present a volume/gain control to the user, which only exists on the Ports of the latter.
Question:
Is it correct, and portable, to assume that there is this apparent 1:1 relationship between a mixer named "<someName>" and another mixer named "Port <someName>"? I have read the entire javax.sound.sampled tutorial, several times. I have read the often-recommended article at http://www.vsj.co.uk/java/display.asp?id=370
several times and while I believe I understand the concepts being presented, the configuration I have doesn't seem to match what is described there.
I've written code to query the audio system on my machine (Windows Vista) and the (shortened) output is below. Java version info:
java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07)
Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode, sharing)
If there is some way to make this question better so as not to require an unreasonable amount of effort from anyone kind enough to answer just let me know.
Thanks.

Shortened code output. Added Exec summary. Trying to make it easy to help.

b) I don't understand the way the system is intended to present a logical description of the sound system
c) My system is bizarre
d) The (only) way I can think of to make this work is actually the correct way - and will be subject to failure on different machines.
I hope it's either option a) or b) - I can fix that; c) is a nuisance, but d) is a worry.Working through this logically...
SourceDataLines are things the user can read from, and TargetDataLines are things the user can write to...
You have SourceDataLines associated with the Speakers and the SPDIF Interface... both of those are outputs, but I think it's safe to assume those two "mixers" are actually loopback interfaces to monitor the outputs.
You have TargetDataLines associated with the CD Audio and Port Line In... both of those are inputs, and writing to them doesn't really make any sense...
It looks like your system is "being helpful" by providing a loopback interface (Master Volume target port) with each output port...
My best guess is that all of the ports with just source lines feed into a common area ("Master Volume") and then all feed out of that common area into a series of mixers that have a loopback SourceDataLine you can monitor the output on and a TargetDataLine that you can write to... and then they leave the system through whatever hardware they are associated with.
If that's not the case, then it's the case that you have multiple parallel paths through your Sound System, and you can "write" to things that should be inputs because those inputs have their own mixers.
Is it a safe bet that it's a 1:1 mapping? Well, I think it's a safe bet that either that's the case, or, it doesn't matter. You could run into problems down the line doing it that way, but, I'd recommend you:
1) Handle a normal system (system with a single port mixer) in the normal way
2) Handle a funky system like yours by assuming "Mixer <Source>" will give you the output of "Port <Source>"...
Because, frankly, I think that "Mixer <Source>" should give you the output of all of the "Port <Source>" that are enabled... or it'll just give you the output of the one Port. Either way, you should be fine.

Can MacBook Pro output digital audio via usb?

I'd like to output digital audio via usb. Can it be done from iTunes? This would allow me to go directly to my dac and then to my preamp.
Thanks.

Russell, there are quite a variety of devices that accept digital audio over USB from any mac with a USB port - see http://www.trendsaudio.com/EN/Product/USBAudiodesc.htm for one example.
Try a google on MAC USB Audio OUTPUT any you should pop up some useful options.
Cheers

KN9 Platinum - is audio output via both SPDIF ports possible??

I am looking at this board because it has both an optical and coaxial SPDIF output - can you tell me whether these can be plugged into and used simultaneously for HD Audio output. ie I want to be able to output a single digital audio stream from an application like PowerDVD via both connections.
Note this is not about multi streams from different applications - just a single stream via both SPDIF ports.
For an HTPC setup I want to be able to take the optical SPDIF output to a surround sound receiver and the coaxial SPDIF output into an HDMI enabled graphics card which includes audio input so I can then take both video/audio to another monitor.
Thanks for your help.
Ben

Yes, audio will do this video won't.

My MacBook Pro has no audio. Sounds preferences showing output is Optical digital-out port. How do I change this to built-in speakers?

I experienced this same problem yesterday on my MacBook Pro, still searching for a solution, several other posts here indicate people have been experiencing this since at lease 2007. I have yet to find a clear solution.
It appears that occasionally inserting headphone causes this, it turns on the Optical digital-out port feature (red light glows inside the headphone port) and takes away the internal speakers option. Restarting did not restore it, but for some reason after sitting asleep overnight the sound started working again and the internal speaker option return in the Sound - Output Window, and the Optical Digital-out option went away.

Simultaneous import of video via firewire and audio via in-line audio port

I have a converter that takes the S-video and audio input from my DVR then converts both to DV format, and then outputs via firewire. I hook the firewire up to my G5, open iMovieHD, and the application recognizes that as a camera and imports wonderfully.
Well, the audio comes through with a MAJOR buzz or hum. It's probably the converter, but the buzz/hum is not enjoyable.
So, I removed the audio from the converter, and the video converts wonderfully in iMovie without the audio. I have the audio coming in through my audio line-in.
I start to import my video, and iMovie starts recording the video. But I want to record the line-in audio at the same time. But when I switch to audio to turn on the input from the line-in, the video stops capturing.
When I start to capture audio first, then switch to capture video, then the audio stops capturing.
Is there any way that I can capture the video via firewire for one "track", and my line-in audio for the other "track", and have them play simultaneously in iMovie during capture??
Any help would be appreciated. thanks Adam

hey there badkitty 42,
i don't think you can do that. it sounds like your issue is electrical. try turning the plug around on each piece of gear in the chain & listen for the buzz. if it's not heard you've found the cause of your ground loop. you can also pick up some of the 3-prong orange or grey electrical adapters from Lowe's or Home Depot to see if you can "lift the ground" to get rid of the buzz. i'd try one on the convertor 1st. one last thing, do you have any flourescent lights in use on the same circuit or in proximity to where you're doing your transcoding? these are notorious for inducing 60Hz hum in audio & video gear.
good luck.

HP Elite 8300 Ultra Slim No Audio via Display Ports -Solution-

This is a solution or a work around to getting audio functionality via the Display Ports on the HP Elite 8300 Ultra Slim and I suspect but cannot confirm as I do not have "other 8xxx models". Normally in the windows sound settings it will offer no options for audio via HDMI, etc with whatever drivers you so happened to install from HP or Intel when using the Display Ports on the machine.
So this is what I did and I replicated it again to be sure.
1.Install the Latest Intel HD 2500 Drivers first from the Intel Website first of course
2.Download the HP Power Assistant Software v2.0.5.1
http://h20565.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_102595_1
and install it and suddenly in the Sound settings in the Windows Control Panel you will find it now shows audio devices that are connected via the Display Ports via HDMI , weird I know but it works for any audio device connected to the DP pots via HDMI, etc.
HP Customer Services told me categorically that it was not a function of the 8300 Ultra Slim supports due to the revision of display port it has so I am a bit annoyed that I had to search and search and actually fix it myself.

Great discovery.
I may experiment on my 8000 and 8200 Elite CMT's.
I would have to remove the video cards I added though.
FYI, so you don't have to go to third party websites, HP does have a direct link to the Power Assistant software you used.

Capturing Audio from DAT

Hello,
I'm trying to capture audio from a DAT deck (Tascam DA-20) into FCP HD by routing it through my JVC BR-DV600U DV deck (RCA output from DAT, RCA input to DV deck, Firewire into FCP).
The DV deck's input is set to line-in, and the audio is being routed through (audio meters on DV deck mimic those on DAT deck, and I can hear the audio through the headphones jacked into my DV deck).
However, when I try to capture the audio on FCP, I am unsuccessful, prompting the following window from FCP: "Error: Final Cut Pro HD was unable to read the movie file just captured."
Now, I use the same set up I described above to capture footage from my Beta deck into FCP with no problems (route Beta signal through DV deck and firewire it into FCP). This leads me to believe that perhaps the glitch lies within my Capture Presets.
At first, I tried to capture the signal as an Audio-Only DV NTSC 48 Khz/Non-controllable device. After that failed, I tried to create my own capture preset, but am not sure it will make a difference, as the only input choices I am given are DV Audio, Built-In Audio, and None.
Any suggestions?
Thanks.

Why not capture the audio content outside of FCP, check the sample rate for 48Khz/16-bit, convert if necessary, save as an AIFF file, and then import that resulting sound file into FCP?
Any good audio app, including STP will do captures.
You are probably going to need to do some cleanup on the audio anyway before you use it, so why not just use an audio app to do it beforehand?
Besides, if you have an audio device (PCI card or Firewire device) in your Mac, you can use the S/PDIF port for your connection to the DAT and do a digital transfer when you import.
As I understand the way you are doing it now, you are taking digital content from the DAT, converting it to analog for the connection into your deck, and then re-converting it into digital when you capture it back into FCP.
One big advantage of digital audio (and video) is to avoid generation loss and added noise during transfer if you go D-to-D.
If you don't have an audio card or Firewire A/D audio I/O device with S/PDIF ports in your Mac, then see if you can find a friend who has one and can do the transfer for you. Then he can give you the file on a CD-ROM.
That's what I'd do.
